Question

ionisation enthalpy and electron gain enthalpy are 1680 and -329 kJ/mol respectively.Its electronegativity in Mullikan scale is ​

Answer 1

$1680 + ( - 329) \div 2$

= 675.5kJ/mol

Answer 2

Answer:

676  

Explanation:

Given:

Ionisation enthalpy = 1680 KJ/mol

Electron affinity = -329 KJ/mol

To Find:

Electronegativity = ?

Solution:

Electronegativity = [Ionisation enthalpy + Electron affinity]/2

Electronegativity = {1680 + [-329]}/2

Electronegativity = 1356/2

Electronegativity = 676
